Getting a django.db.utils.OperationalError: no such table With a Custom User Model

Question

Well, I have a custom User Model in an app called accounts. The accounts.User looks like this:

from django.contrib.auth.models import AbstractBaseUser
from django.core.validators import RegexValidator
from django.db import models
from django.db.models.signals import post_save
from django.dispatch import receiver

from accounts.managers import UserManager
from base.models import Model
from accounts.models.profiles import Profile


class User(Model, AbstractBaseUser):
    objects = UserManager()

    phone_regex = RegexValidator(
        regex=r'^\+?1?\d{9,15}$',
        message="Phone number must be entered in the format: '+999999999'. 9-15 digits allowed.",
    )
    phone = models.CharField(
        validators=[phone_regex],
        max_length=17,
        blank=True
    )
    email = models.EmailField(
        max_length=255,
        unique=True,
    )
    active = models.BooleanField(
        default=True
    )
    staff = models.BooleanField(
        default=False
    )
    superuser = models.BooleanField(
        default=False
    )

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = []

    def __str__(self):
        return self.email

    def has_perm(self, perm, obj=None):
        return True

    def has_module_perms(self, app_label):
        return True

    @property
    def is_active(self):
        return self.active

    @property
    def is_staff(self):
        return self.staff

    @property
    def is_superuser(self):
        return self.superuser

    def serialize(self):
        data = {
            'id': self.id,
            'email': self.email,
        }
        return data


@receiver(post_save, sender=User)
def create_profile(sender, instance, created, **kwargs):
    if created:
        Profile.objects.create(user=instance)


@receiver(post_save, sender=User)
def save_profile(sender, instance, **kwargs):
    instance.profile.save()

and the UserManager looks like this:

from django.contrib.auth.models import BaseUserManager


class UserManager(BaseUserManager):

    def create_user(self, email, password):

        if not email:
            raise ValueError('Users must have an email')

        if not password:
            raise ValueError('Users must have a password')

        user = self.model(
            email=self.normalize_email(email),
        )

        user.set_password(password)
        user.save(using=self._db)
        return user

    def create_staffuser(self, email, password):

        user = self.create_user(
            email=email,
            password=password,
        )
        user.staff = True
        user.save(using=self._db)
        return user

    def create_superuser(self, email, password):

        user = self.create_user(
            email=email,
            password=password,
        )
        user.staff = True
        user.superuser = True
        user.save(using=self._db)
        return user

And my accounts app registered like this:

...

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'base',
    'accounts',
]

AUTH_USER_MODEL = 'accounts.User'

...

I run python manage.py makemigrations and python manage.py migrate and everything run smooth as expected. The problem happen when I start to python manage.py createsuperuser. It prompts to give an email input as expected but when typed an email and click enter it returns me an error.

The above exception was the direct cause of the following exception:

django.db.utils.OperationalError: no such table: accounts_user

What I'm trying is I tried to reproduce the error by deleting the database and doing the migration and I found there is no migration file created in my app as expected because it supposed to have migration file of my custom user created in the database. Anyone had this error before? And how did you resolve it?

Remove all files in your migrations folder inside your accounts app except init.py. Then try to run migrate again. After that use sqlitebrowser to open the database file created and see if the user table has been created. — MiniGunnR

The problem solved by manually recreate migrations/ folder in my app. The folder was deleted when I dropped my Database and Migration Files. The folder doesn't recreated automatically with python manage.py makemigrations and python manage.py migrate.

When creating custom user model from AbstractBaseUser you dont need to add Model class as parent, just leave AbstractBaseUser:

class User(AbstractBaseUser)

After this clear migrations file and rerun makemigrations and migrate.
